Marx suggested that hitherto history is a series of class struggles - and even the great changes in America in the twentieth century occurred as a result of massive struggle. The New Deal wasn't FDR's "gift" to America - it was a concession by the bourgeois class in response to the massive labor movement that actively struggled. And black people weren't "handed" legal equality by Johnson - they won it over a decade of active struggle. At the time, the ruling class wasn't ready for millions of protesters in DC - I'm sure it scared the shit out of them. Great changes in the system are won by our class by struggle, but as the system develops to encompass those changes, it co-opts the institutions of struggle. Labor unions in the US today are effectively reactionary, often in consciousness but specifically in their functional role. They haven't fought for wage increases in years - accept against inflation. Unions have become wholly defensive institutions, co-opted into the contradictions of labor and capital. And as such, they have taken such shape to be conducive to this occurring.
But the movements have only accomplished small-scale changes - our goal is the complete destruction of capitalism and the eradication of wage-slavery.
We have to encourage struggle outside official channels of class mediation. We can't be suckered into politics - we want 10 million workers in the streets of every city, physically taking them for working-class rule. We have to encourage, then, any and all resistance to capital (including its component component imperialism), in all shapes and forms. And we must provide reasoned argument for further measures of resistance. We want people striking from all work, marching in the streets, and, ultimately, executing capitalists. How we can instigate this is up to further discussion.
But it can't be "lead" by philosopher-kings or enlightened despots.
